Application med September 28, 1925. Serial No. 59,197.

'This invention relates to valves and more particularly to a valveadapted for use in connection with a'pressure chamber having a membertherein adapted-to beoperated by differential pressure controlled bythe'valve.

'In'my prior Patent No. 1,522,692, I have shown and described anattachment for nic tor vehicles comprising; a cylinder, a piston mountedthereinand adapted to be moved fold of an automobile engine.

in one direction by differential pressure and to be returned to normalposition by a spring, and a plurality of pivoted leaves adapted to beactuated by said piston to form a'glare shield-for use in connectionwith motor vehicles. "In the present case I haveillustrateda' similardevice wherein a source of pressure or vacuum is adapted to beconnected, to either end of the cylinder to operate the'piston, thespring means being omitted. The subject matter of the present inventioncomprises a novel form of valve.

adapted to control communicationbetween the opposite ends of thecylinder andfa source of such vacuum as the lntake inani- An importantobject of the invention is to provide a simple form of valve structurehavingnovel means for affording communication between one end of thecylinder of the glare shield and the atmosphere.

A still'further object is to provide a valve of the above mentionedcharacter wherein each of the portsprovi'ded in the valve may be drilledtherein thus simplifying the construction and making it cheaper tomanufacture.

Other objects and advantages of the invention will become apparentduring the course of the following description.

In the drawings I have shown'one embodiment of the invention. Inthis'showng: V

66 of Figure 5, and,

is a central vertical sectional View Figure 1 is a faceview of the glareshield shield, parts being shown 1 Figure 7 is a similar view on line7,7

of Figure 6. 1

Referring to the drawings, the numeral 10 designates a motor vehiclehaving an engine 11 provided with the usual intake manifold 12. Thevehicle is provided witha windshield 13 mounted in the usual frame 14.

A supporting member 15 is secured to the windshieldand is provided witha substan-; tially' U-shaped depending portion 16 adapted to receive aplurality of leaves 17 pivotally connected to the support as at .18. One1 of the. leaves 19 is provided with a pin 20 secured thereto andextending transversely from the inner face thereof. Each of the otherleaves is provided with an arcuate extension 21 having a slot 22 thereinto receive the pin 20. Each of the slots 22 is progressively longer ineach of the extensions 21 from, the leaf 19 to the farthest leaf 23.

Thus it will be apparent that the lifting of .the leaf 19 fromtheposition shown in Figure 2 to the positions indicated in Figures 1 and 4will cause the other leaves to be successively raised, thus providing ineifect'a.

solid sheet to act as a glare shield. The leaf 19 is provided on theopposite side of the pivot 18 with an extension 24: having a slottherein. The extension 2 1 extends through a .slot 26 formed in acylinder 27. A 'piston'28 is mounted to reciprocate in the cylinder 27and is provided with atransverse pin.29 adapted to engage within theslot 25ito move .theleaf 19 upwardly, when the piston 28 travelsdownwardly? in the 7 cylinder. Pipes 30*aind 31 communicate with eitherend of the in. Figure 2. v 7

'Referring to Figures 5, 6 and 7 the me cylinder 27, as shown meral 32designates a substantially cylin-ZY drical valve body havinga taperedopening 33 to receive a similarly shaped valve 34. a

The valve is provided with a radialopening 35 extendingentirelytherethrough andthis opening communicates with'a second radial opening36 drilled half way through the valve and at right angles to'the opening35., The valve is provided opposite the opening;

36 with an angular port 37 the upper en of which is arrangedsubstantially in the same plane as the openings 35 and 36. The

valve body is provided with opposite alined openings 38 and 39, and isfurther provided with a radial vopening 40 arrangedbetween and in thesame plane as the openings 38 and 39. The openings in the valve bodyjust deill scribed are obviouslyarranged in the same plane as theopenings 35 and 36 and the upper end of the port 37 to communicate therewith under certain conditions to be described.

The valve body is provided at its upper end with shoulders 41 adapted tocontactwith pins 42 carried by the valve to limit rotating movement ofthe latter. The valve is provided at its upper end with an enlarged head43 having an operating handle 44 connected therewith Tlie'lower end ofthe valve 34 is arranged substantially flush with the lower end of thevalve casing and a washer 45 is arranged thereagainsti The lower end ofthe valve is internally threaded to receive the threaded end of a plug46' having an enlargedhead 47 adapted tocontact with the lower face'ofthe washer 45; The plug 46 is provided with an axial opening 48communicating with the lower end of the port 37. 'Each of the openingsand ports previously described in connection with the valve, casing andplug is formed by drilling whereby the structure may be cheaplymanufactured; In the drilling operation, the

openings 35, 38 and 39 may be drilled in a singleoperation after whichthe valve may berotat'ed' onequarter of a turn to permit drilling of theopening 3Gthrough the opening 39: Theport 37 may be drilled through theside of the valve before the latter is placed-in position.

The'pip'e'31 is connected to the valve casingby a-suitable union 49'whereby it communicates with: the opening. 38, while thepipe 30 may be?similarly connected to the valvecasing-by a union 50' to affordcommunication with the opening 40. A' third pipe 51 is connected to thevalve casing by a union 52 whereby it communicates with the opening39,-the'oppositeend of the pipe 51 being connected with the: intakemanifold- 12 to communicate therewith as shown" in Figure 3. The valvebody may be mounted in any convenient place accessible-to the driver ofthe vehicle and in the-present instance I have illustrated a'bracket153conmunication will be afforded between the lower end of the cylinder 27and the intake mai'iifold through pipes 31 and 51 and openings 35, 38and 89. The upper end of the cylinder 27 will communicate with theatmosphere through pipe 3O, opening 40, port- 37 and opening 48 topermit air to enter the upper end of the cylinder 27 whereby the pistonmay freely move downwardly. This action depresses the arm 24, liftingthe leaf 19 and the succeeding leaves to provide a glare shieldsubstantially of the character shown in my prior Patent No. 1,522,692referred to above. As long as the valve remains in the position shown inFigure 5,.

ing 38,-port 37 andiopening48, thus allowing.

free upward movement of the. piston 28.

The upper end of the cylinder 27 willbe-in.

constant communication with the intake manifold when the leaves of theglare shield are in inoperative position and the suction of the manifoldtends to hold the leaves in inoperative position to prevent rattlingthereof.

It isto be understood that the form of my invention herewith shown anddescribed is to be taken asa preferred example'of the same and thatvarious changes in the shape,

size and arrangement of parts may, be. re-

sorted to without departing from the spirit of the invention or thescope of the subjoined claim I claim: 7

A device-of the character describedcomprising asubstantially cylindricalvalve body provided in its sides with an. inlet openin-gand a pair ofoutlet openings arranged in the same plane at right angles to the axisof said valve body, and a rotatable valve arranged in said valve body,said valve being provided with an opening. extendingdiametricallytherethrough andan opening.

extending halfway therethrouglr at right angles to andcommunicating-with said last named opening, said valve being furtherprovided with an inclined vent port, oneen'd of said port and theopenings in said-valve.

being arranged in the same plane as the openings in said valve body,said-valve be' ing provided in one end with athreaded] axial opening,and a plug threaded insaid axial opening and provided with an openingcommunicating with the other end ofsaid port, said plug being adapted tomaintain said valve in said valve body.

In testimony whereof- I aitixmy signature.
